Labeling Walls with Fire Rating

Q: Is there an NFPA code requirement for labeling fire / smoke rated walls above ceiling and if so what is it?

A: No… there is not a NFPA code or standard requirement to label the walls above the ceiling. But I’ve been told there is an IBC requirement, but I cannot provide you with any confirmation of that. I’m not a big fan of labeling the walls above ceiling with their hourly ratings, or even whether or not they are fire-rated walls or smoke barriers, etc. The reason why; it often can be labeled incorrectly… then what does a surveyor do if the walls are labeled one way and the LS drawings show something different? It creates confusion and opens the door for a finding by the surveyor. If you don’t have to do it, I suggest you do not.
